Conducted in April 1932 at the [[University of Cambridge]], England, physicists Cockroft and Walton successfully split [[lithium]] atom [[nucleus|nuclei]] by colliding them with artificially accelerated protons. This experiment is general hailed as being the first [[transmutation]] of an element using artificially accelerated particles, for which they were honored with the [[Nobel Prize]] in 1951<ref>http://www.nobelprize.org/nobel_prizes/physics/laureates/1951/</ref>.
